I found one for gv-13 at http://lfiles3.brothersoft.com/photograph_graphics/image_viewers/irfanview_plugins_433_setup.exe
It works perfect. But after I saw link by domifer, I updated it, but this FW only shows 1GB internal NAND storage and not mounting any SD card.
Anybody have any idea, what going wrong.
Now when I try to revert back to above firmware, it adort with error.
